Pressure Relief Procedure

Pressure Relief Procedure Pressure Relief Procedure Pressure Relief Procedure
Pressurized Equipment Hazard
The system pressure must be manually relieved to pre-
vent the system from starting or spraying accidentally.
To reduce the risk of an injury from accidental spray
from the gun, splashing fluid, or moving parts, follow
the Pressure Relief Procedure whenever you:
•
are instructed to relieve the pressure,
•
stop spraying,
•
check or service any of the system equipment,
•
or install or clean the spray nozzle.
1. Lock the spray gun safety latch.
2. Shut off the power source to the pump.
3. Close the bleed-type master air valve (required in
the system).
4. Unlock the spray gun safety latch.
5. Hold a metal part of the spray gun firmly to the side
of a grounded metal pail, and trigger the gun to
relieve fluid pressure.
6. Lock the spray gun safety latch.
7. Open the pressure relief valve, having a container
ready to catch the drainage. Leave the valve open
until you are ready to spray again.
8. If you suspect that the spray tip/nozzle or hose is
completely clogged or that pressure has not been
fully relieved after following the steps above, very
slowly loosen the tip guard retaining nut or hose end
coupling to relieve pressure gradually, then loosen
completely. Now clear the tip/nozzle or hose.
